Little pricey, but LeoVince makes a high quality exhaust for the People 250. Also Look at my pictures I've posted, I got a used Yoshimura RS-3 and a header made for a different 250 muffler, welded it up and BOOM, best sounding 250 exhaust I've ever heard. All in all, i think I paid $80 for the Yoshi, $50 for the header and like $40 to get it mig welded. It's very open compered to most of the exhausts made for the 250 engine are sill pea shooters.
